Water-based painting mix

It’s a good idea to be fairly generous with the amount of paint you mix.

Don’t worry about waste, it will keep if you place it under a jam jar with a water seal it can be rehydrated the following day.

– Put a tablespoonful of paint on your palette and pat it down to a 5mm ‘pancake’. – Then take about a sixteenth of a teaspoon of powdered gum Arabic – yes, a tiny bit! – on the end of your palette knife and tap it gently over the flattened paint, so it looks like the first falling of powdery snow.

– Use a pipette to add water – it’s more controllable and stays clean.

– Make a well in the middle of your dry paint and gum Arabic, and start adding water a bit at a time.

– You don’t want to add too much otherwise you’ll have to add more paint and more water and more paint…

– Take all the paint up and mix to a thick yogurty consistency.

4 Grinding the paint

Thankfully paints these days are ground extremely finely by machines – otherwise you’d be up for half an hour of arm ache.

Instead, a few minutes of dedicated grinding of the paint should be enough.

– The palette knife should be used to grind the paint in a circular motion, with some downward pressure. It’s ready when it’s a smooth paste.

– Repeatedly scrape it up together neatly – you don’t want it all over your palette.

Don’t add too much water at this stage – the main bulk of the paint is used as a ‘reservoir’ from which you take small amounts as needed from the edge before watering it down further.

5 Testing the paint

I expect you’re wondering when in these glass painting instructions you’re going to learn just what to do with the icing sugar?!

The gum or sugar is used both as a vehicle to help the painting flow and to adhere it to the surface of the glass.

You need to have the correct ratio, otherwise the paint will be too sticky and bubble when firing, or not stick sufficiently to the glass. This is the time to test it and see.

– Use a painting brush with a bit of additional water and make a couple of lines of paint on clean glass.

– Let them dry and then gently, with a dry fingertip, rub over the surface of the paint. It should be resistant, but not stubborn to your touch. Try scratching into it with a toothpick – it should come off fairly easily.

– If you have trouble scratching it off, you have too much gum, and need to add more paint.

– Conversely, if it falls off with hardly a touch, you need to add more gum.

– Mix this with a little water before adding to the mix, and re-test.

– Testing your paint isn’t a once-only job – you should often be giving it a quick test to make sure its’ composition hasn’t radically changed.

About Me

I'm Milly Frances and I've been working with stained glass for over - yikes! - 20 years now, both as a professional artist and as a trained teacher. I also play 5-a side football (badly).
My biggest love is working alongside people early in their stained glass journey and giving them the confidence to find their own artistic direction.
